6'9? Is there anybody that tall in the MLB?
Gene Conley. Boston Braves and Boston Celtics. Yes, the guy who was a backup to Bill Russell, and a spot-starter and relief pitcher for the '50s Braves. Could say that he backed up Warren Spahn as well as Bill Russell. One World Series ring (1957), two pennants ('57 and '58), and a slew of NBA championships. Same teams as Henry Aaron and Bob Cousy.
Frank Howard was 6'7 or 6'8, and probably played basketball at Ohio State...
